A successful coral reef aquarium depends on how well you maintain the water parameters which are the key to a stable coral environment. All of the elements found in natural seawater play a role in providing optimal water parameters, but some are more significant than others. These elements, the foundation of the reef environment, include the three major elements: Calcium (Ca), Magnesium (Mg) and Carbonates (CO3). All three have a major effect on water chemistry (pH stability, Alkalinity, ionic strength) and on many of the coral's biological processes (skeleton formation, ions exchange, photosynthesis).The foundation elements complement each other in the formation of coral skeleton. If not balanced correctly one of the elements will quickly limit healthy coral growth.Maintaining balanced levels of the Foundation Elements (Ca, KH Mg) creates optimal water conditions for promoting strong and healthy coral growth. Reef Foundation A is a Calcium Strontium complex for balanced formation of Coral Skeleton.Reef Foundation A: Contains Calcium, Strontium, and Barium according to the ratios found in coral skeleton. Concentration: 1ml will raise the Ca level of 100 liters (25 gal) by 2ppm.

Red Sea calcium, magnesium, strontium and carbonate are the basic foundation elements of coral skeletons. All of these elements need to be available in balanced proportions for coral health and growth. Reef foundation C contains blended salts of magnesium and is part of complete reef care system. 1-mL of reef foundation C will raise the magnesium level of 25-gallon of water by 1 ppm. Includes a convenient measuring cup for easy dosing. Available in 500-ml bottle.
